8. X-Men: The Last Stand (2006)

Alternate endings are often a symptom of a production that hasn't settled on a plot. You can usually tell which movies suffer from alternate or multiple-ending syndrome — because they tend to suck.

X-Men: The Last Stand, by far the weakest in the franchise, featured no less than three alternate endings. One where Beast returns as a teacher to the Xavier Institute, another where Rogue gets to keep her powers and the one seen above, where Logan heads back to the Alberta tavern where he likes to drink.

Would any of these sequences really make this tepid sequel better? No. It's probably better to pick a story and stick to it.
